6-7 BTDC ok for TBI 454?

All -

In my never-ending quest for just a smidge more power and maybe better MPG, too, I started playing with timing yesterday.

I went from the stock 4 degrees BTDC to somewhere around 6-7. She seems a bit more perky all-around, definitely a lot less throttle needed to get up and around.

I also hooked up my 1320 scan tool using the ALDL scan tool app. Knock count is 1-2 knocks on heavy throttle, maybe one or two at startup, and about 6-8 at shutdown.

I don't hear pinging, but I admittedly I'm not sure I know what I'm listening for.

So, aside from having to adjust it back before its next CA smog check, am I ok?

You'll be fine,mine's set at 8 BTDC.I see you've discovered these engines like a little more advance and respond well to it.Whenever it's time to Smog it I set back to 4 BTDC and all is well.

I thought 0 was stock? Either way, step up to premium gas and you can eek a few more degrees of timing from it.

0 for 350s I believe,4 b4 on big blocks

Ahh, well that's where I got my zero from.
